What are the characteristics of superimposed hydraulic control check valves

The superimposed hydraulically controlled check valve combines the compact structure of the superimposed valve and the reverse flow function of the hydraulically controlled check valve. It has the characteristics of compact structure, simple installation, high system integration, accurate control, wide application scenarios, and convenient maintenance. The specific details are as follows:

Compact structure and small size: the superimposed hydraulic control check valve adopts a superimposed design and can be directly superimposed on hydraulic valve blocks or other valves without the need for separate connection of pipelines. This design significantly reduces the system's volume and weight, making the hydraulic system more compact.

Easy installation and short assembly cycle: Since the superimposed hydraulically controlled check valve does not require special installation skills and the components are connected without pipes, the installation process is simple and fast, and the assembly cycle is short. This helps reduce installation costs and improve production efficiency.

High system integration and flexible configuration: the superimposed hydraulic control check valve not only has control functions, but also plays the role of oil passage. By adding or decreasing the superimposed valve, the changes in the hydraulic system can be easily achieved and the requirements of different working conditions can be met. At the same time, its standardization, generalization and integration are relatively high, making the system configuration more flexible.

Accurate control and stable performance: the superimposed hydraulically controlled check valve relies on controlling the fluid pressure to achieve reverse flow of the check valve. When the control oil circuit has a control pressure input, the piston push rod moves under the action of pressure oil, opens the check valve, and connects the oil inlet and outlet, achieving reverse flow. This control method is accurate and reliable, and has stable performance.

A wide range of application scenarios: superimposed hydraulic control check valves have many application scenarios in hydraulic systems. For example, in a vertical hydraulic cylinder, it can prevent the piston and piston rod from sliding down; in a system that requires pressure maintenance, it can use the tightness of the cone valve to close and keep the oil passage for a long time; when the hydraulic cylinder is locked, it can tightly seal the oil in both chambers of the hydraulic cylinder; in a large-flow oil discharge system, it can smoothly discharge the oil; in addition, it can also be used as an oil filling valve, or combined into a reversing valve, etc.

Convenient maintenance and low cost: The superimposed hydraulic control check valve has a compact structure, small size and light weight, making installation, replacement and repair more convenient and quick. At the same time, since there is no pipe connection between the components, leakage, vibration and noise caused by connections such as pipe fittings, oil circuits, pipe joints, etc. are eliminated, reducing maintenance costs.
